All image sensors that I am aware of are clickpads, with one button
integrated under the pad, which is reported as the middle button.
We could report right, middle, up, down, and ext_buttons (scroll is
not possible, since w=2;buf[1] is used for x for devices that send agm
packets).
However, I have no way of knowing if this added complexity is
necessary, nor any way of testing it.
